"Why, Kenny! What on earth do you think you're doing on that thing?"

Cheryl's eighteen year-old kid brother was sitting on the exercise machine in his bedroom, stark naked, grimacing as he worked his way through a set of leg raises. He let the weight fall and looked at his sister sheepishly as she walked in.

"Oh, hi, Sis. I was just trying to iron out a few kinks, that's all." He smiled unconvincingly. "The knee's starting to feel a lot better, Sis! Really! I mean, all I've got to do is get the blood flowing in it, and I hardly know it's hurt at all!"

"That's nonsense, Kenny, and you know it. You know the doctor told you that the best way to treat it is to just lie right on your ass in bed and let it heal itself."

"But it seems so silly! I can walk fine."

"I don't care if you can do jumping jacks, Kenny! The only reason we're going to Metro City is to get you onto the college varsity team. And what you can't do while your knees still hurts is kick like you used to. So get off that machine and get in bed this instant!"

Kenny sighed, then obediently slid off the exercise machine and walked stiffly back to the bed.

Cheryl smiled warmly again as the naked youth slid onto the sheets, bunching several pillows behind his back. And she glanced automatically at his big, meaty prick as she sat beside him on the mattress.

"What it needs is surgery," Kenny mumbled.

"Yes, I know that, dear," Cheryl sighed. "But we just don't have the money for any of that stuff. The next best thing is bed rest. Now, I want you to keep being optimistic, Kenny. I'll find a job in Metro City that'll pay rent money and your tuition in college. All you've got to do is keep that leg healthy so you can impress Coach Walsh at try-outs and get onto the varsity team."

"All right," Kenny sighed dejectedly.
